NEW YORK, N. Y., A CORPORATION OF NEW YORK ASSOCIA'I'ING MECHANISM FOR WEB.PRINTING MACHINES Application filed January 17, 1931.

The present invention relates to associating mechanism for web printing machines in which a relatively wide web is cut into ribbone which are associated or brought together face to face, with their edges in alignment and are subsequently cut and folded to form a mnlti-leaved product.

This result has been produced in the past by leading the tall width web through a mula tiple slitting mechanism after which each of the ribbons thus formed is led over a series oi turner bars and rollers to associate it with the other ribbons before they are cut and.

folded.

This arrangement is objectionable because i it is diiticult to lead the narrow ribbons around a series of turner bars and keep them running in proper alignment and avoid breaking the web.

In the mechanism herein disclosed, each narrow ribbon passes around but one turner bar and in consequence the several ribbons are held in proper alignment without (lifticulty and without subjecting them to an excessivc strain.

The improved associating mechanism is particularly adapted to printing machines with so-callcd straight-away folders, where sometimes the web is run straight through the folder, while at other times the web is slit into ribbons which are then collated and run through the folder.

The improved associating mechanism is especially adapted for use with printing machines having :tolders arranged in line with the printing units and which may be used at one time to print a product having large pages such as a newspaper and at another time to print a product having relatively small pages such as a magazine.

An object of the invention is to provide an inn n-oved associating mechanism for a web printing machine, that is adapted to cut a wide web into several ribbons and to associate the ribbons which are then led toa cutting and folding mechanism whereby a multi lcaved product is produced.

r inother object oi the invention is to provide an improved associating mechanism for a web printing machine that sometimes Serial No. 509,286.

used to print products having large pages and at other times, productshaving relatively small pages.

Itis. also an object of the invention, to pro-' vide an associating mechanism ,ofgenerally improved construction, that will be simple,

Withthe foregoing and other objects in iew, which will appear as the. description proceeds, the invention resides in the combination and arrangement of parts, and inthe details of construction hereinafterdescribed and claimed, it beingunderstood that various changes inrthe precise embodiment of the invention herein disclosed may be :made within the scope 01": what is claimed without departing from the spirit of the invention.

The preferredembodiment of the invention is illustrated in the accompanyingdrawings wherein Figure 1 is a diagrammatic side view of printing machine and folder such as are used for producing magazines, and showingthe arrangement of the improved associating mechanism;

Figure 6 is a plan view of the arrangement shown in Figure 5.

Referring to the. drawings, 11 and 11 indicate impression cylinders of a printing machine, while 12 and 12. indicate form cylinders, and inking mechanism is indicated gen erally at 13and 1 A -io1der is indicated generally at 1.4 as

--' thence to the nipping rollers 35.

shown in Figure 1, and comprises cutting cylinders and 15, a collecting cylinder 16, a folding cylinder 17, a delivery fan 18 and delivery tapes 19.

A web roll is indicated at 21 from which a web 22 is led around suitable guide rollers 23 and feeding rollers 24, thence to and between the printing cylinders 11 and 12, thence around guide rollers 25, to and between the printing cylinders 11 and 12', thence around guide roller 26 and compensating roller 27, to guide roller 28, thence around a turner bar 29 to the slitting mechanism, which comprises a slitting roller 31 and slitters 32. It

- is thus cut into several ribbons, each of which pass around one of the small turnerbars 33 and one of the guide rollers 34 from which it passes into face to face relation with the other ribbons and they are associated at the nipping rollers 35. From that point, they pass to the cutting and folding cylinders and the product is delivered in the usual manner.

The machine shown in Figure 1 is of the kind used for producing magazines and hence is provided with an offset web roll shown at 36, the web 37 from which is led around guide rollers 38 and between the web 22 and the impression cylinder 11, thus preventing smutting of the side of the web that has been printed by the form cylinder 12. The offset web is then led around guide rollers 39 and rewound on the roll 41 which rests on the rollers 42.

It will be seen that by this method of associating the several ribbons into which the web is cut that but one turner bar is interposed in the path of the web between the slitting mechanism and the folder, and thus the diiiiculty experienced when narrow webs are drawn around double turner bars is avoided.

An alternative web run is indicated by dotted lines in Figure 1 and extends from the roller 28 around guide roller 43, compensating roller 44, to guide roller 45 and This run, it will be noted, by-passes the turner bars and may be used when a full width web is fed to the cutting and folding cylinders, so that the sheets may be delivered separately instead of being associated by passing them around the turner bars.

In Figures 3 to 6 inclusive, the invention is shown as applied to a printing machine that is adapted to print either newspapers or magazines. A typical newspaper printing machine having three perfecting units and a folder is shown, the units being indicated generally by the letters A, B and C and the folder by the letter F. The printing unit A includes impression cylinders A11 and A-ll, form cylinders A-12 and A12 and inking mechanism indicated generally at A13 and A'l3'.

The folder includes a former indicated at 51 and also cutting, folding and delivery mechanism, not shown. The several printing units and the folder are arranged in line in accordance with the usual practise. The former is one-half the width of the web and is so placed that a one-half width web may be run directly to the former without being turned. Web slitting mechanisms are shown and include the slitting rollers 52 and slitters 53. lVhen printingnewspapers, the web 54, that is printed by the printing unit A is led from the web roll 55, around guide rollers 56, to and between the printing cylinders A-11 and A12, around guide rollers 57, to and between the printing cylinders A11 and A--12, around guide rollers 58 and around the slitting roller 52 where it is divided into.

two ribbons that are designated 54a and 54b.

Ribbon 54a passes around guide rollers 59 to the drag roller 61 and thence to the former 51, while ribbon 54?) passes around turner bars 62' and 63 which bring it into face to face relation and in alignment with ribbon 54a, and it then passes around guide rollers 64 and to the drag roller 61 where it is associated with the ribbon 54a.

The webs printed by the units B and C follow similar paths from the web rolls 65 and 66 respectively to the folder.

Figures 5 and 6 show the same printing machine that is depicted in Figure 3 but with,

web runs adapted to produce a magazine or a product having relatively small pages. In this arrangement, the B unit is silenced and webs are being printed by units A and C only, although it will be understood that provision may be made for using the B unit as well. In this arrangement, the web 54, after having been printed by the unit A is led around the roller 52 but the slitters 53 have been removed. The full width web is thus led to and around the turner bar 62 and thence to the slitting roller 67 where it is engaged by slitters 68 and thus cut into ribbons indicated 640, 64d, 64c, and 64f. The several ribbons are each then led around one of the turner bars indicated by the numeral '69 and the guide rollers 71 which position the several ribbons in face to face relation with each other and they are then led to the drag roller 61 where they are associated and passed over the former 51 to the cutting and folding mechanism.

The web printed by the C unit is likewise turned and then slit into ribbons and led to the folder as shown in Figure 6.

It will be noted that the several ribbons as shown in Figure 6, are presented to the former 51 in the same relation as the ribbons shown in Figure 4 so that a longitudinal fold will be made in the center of the ribbons as they pass over the former. The arrangement thus permits the production of a newspaper or a product having relatively large pages by leading the webs as shown in Figure tit] a or a product having relatively small pages by leading the webs as shown in Figure 6.
